# Phase 14 Research: User Directory View

## What Exists (Phase 13 Deliverables)

### ViewModel Properties for Directory Browse
- `IsBrowseMode` (bool) — toggles Search/Browse mode
- `DirectoryUsers` (ObservableCollection<GraphDirectoryUser>) — raw directory list
- `DirectoryUsersView` (ICollectionView) — filtered/sorted view, default sort DisplayName asc
- `IsLoadingDirectory` (bool) — true while loading
- `DirectoryLoadStatus` (string) — "Loading... X users" progress text
- `IncludeGuests` (bool) — in-memory member/guest filter
- `DirectoryFilterText` (string) — text filter on DisplayName, UPN, Department, JobTitle
- `DirectoryUserCount` (int) — filtered count
- `LoadDirectoryCommand` (IAsyncRelayCommand) — disabled while loading
- `CancelDirectoryLoadCommand` (RelayCommand) — enabled only while loading

### Existing People-Picker (Search Mode)
- `SearchQuery` → debounced Graph search → `SearchResults` dropdown
- `AddUserCommand(GraphUserResult)` → `SelectedUsers` collection
- `RemoveUserCommand(GraphUserResult)` → removes from SelectedUsers
- `RunCommand` → `RunOperationAsync` → audits SelectedUsers against GlobalSites

### GAP: No SelectDirectoryUserCommand
SC2 requires "selecting a user from directory list launches existing audit pipeline."
Need a command that:
1. Takes a `GraphDirectoryUser` from the directory DataGrid
2. Converts it to `GraphUserResult` (same DisplayName + UPN)
3. Adds to `SelectedUsers` via existing `ExecuteAddUser` logic
This is ViewModel work — needs to be done before the View XAML.

### Current View Structure (UserAccessAuditView.xaml)
- Left panel (290px DockPanel): Users GroupBox + Options GroupBox + Buttons StackPanel
- Right panel: Summary banners + Filter/Toggle row + DataGrid (ResultsView)
- Status bar: ProgressBar + StatusMessage

### Available Converters
- `BoolToVisibilityConverter` — true→Visible, false→Collapsed
- `InverseBoolConverter` — inverts bool
- `StringToVisibilityConverter` — non-empty→Visible, empty→Collapsed

### Localization
- No directory.* keys exist — need to add ~10 keys for EN + FR

## Plan Breakdown

1. **14-01** (Wave 1): Add localization keys + `SelectDirectoryUserCommand` on ViewModel + code-behind event handler
2. **14-02** (Wave 2): Full XAML changes — mode toggle, conditional Search/Browse panels, directory DataGrid, loading UX
